Toler and his brother David (Frankie) Toler were members of the Gregg Allman Band in the 1980s,[3] featuring hit album I'm No Angel 1987 and Just Before The Bullets Fly 1988 as well as a reformed version of Great Southern in the 2000s. Dan experimented with jazz fusion multi instrumentalist Mark Pettey in Sarasota in the early 1990s, recording a short demo, and performing live shows in the Tampa Bay area. Mark and Dan continued to collaborate on jazz influenced projects together.

Toler, John Townsend, Toler's brother David (Frankie) Toler, Bruce Waibel and Mark Pettey created the Townsend Toler Band in the early 1990s, starting with a demo cut in Telstar Studios in Sarasota. This was followed by tours of the eastern United States, including shows in New York City and up and down the east coast. He later joined The Renegades of Southern Rock, whose members included George McCorkle, John Townsend (formerly of the Sanford-Townsend Band), John McKnight, Jack Hall and Taylor Caldwell.

In 2007 Toler performed on Jason Black's Mind Over Matter album. Two years later, Toler once again teamed up with John Townsend to form the Toler/Townsend Band. Their self-titled album was released in 2009 on the European Blues Boulevard/music avenue label. The Toler/Townsend Band CD was later released in the United States by Garage Door Records and is getting National airplay.

In 2011, Toler formed The Toler-Tucci Band, which was scheduled to release their debut album, Doc's Hideaway, in August 2012. Verceal Whitaker of The Platters was the featured vocalist on that project.
